Screen a counterparty before payout

1Run the sanctions gate

Start with the C2 sanctions check on the destination. A match stops the payout before any C3 spend.

curl https://api.1st-node.com/v1/aml/eth/0xdead.../sanctions \
  -H "Authorization: Bearer sk_live_..."
> { "match": false }

2Score the destination

For a clean result, request the risk score to measure exposure. This C3 call returns the level that gates the release.

curl https://api.1st-node.com/v1/aml/eth/0xdead.../risk \
  -H "Authorization: Bearer sk_live_..."
> { "score": 12, "risk_level": "low", "confidence": 0.82, "exposure": [] }

3Gate the release

Only release on a clean sanctions result and an acceptable risk band. Anything above your review threshold holds the payout for manual sign-off.

4Store the payout decision

Record the sanctions result and risk response against the payout id. This is the evidence that the destination was screened at release time.
